I know there a like 6 or 8 threads on this but my situation is a little different. I was trying to install in optima yellow top battery and after i hooked up the positive and neg the alarm went off I tried to quickly disconnect the neg terminal I did but the jeep was smoking from between the motor and the drivers tire . I checked fuses 30 amp under hood was blown replaced it put old battery back in. still says service electric system and clicks like its dead so I jumped it. it started on second try. ran for a few mins (long enough for me to put cables away I got in it and revved it up a little and the lights started to dim a little I did it a few more times and it died. It does have a check eng light on but I do not have a scanner.
